I Specification of Letters Patent.

Application filed October 11, 1910. Serial No. 586,502.

To all whom it may concern:

Be it known that we, WARD B. ROWLAND and RIQHARD B. GRovER, citizens of the United States, residing at Pasadena, in the county of LosAngeles, State of California, have invented a new and useful Weighing Device, of which the following is a specification.

This inventionrelates to weighing mechanism for-refrigerators.

The object of the inventionis to provide an apparatus of this character which shall be thoroughly accurate in indicating the quantity of ice contained within the refrigerator; which will operate underall conditions irrespective of the position occupied by the ice upon it, and which shall be thoroughly sanitary, and easy-to remove'for the purpose of cleansing the refrigerator.

Withthe above and other objects in View, as will appear as the nature of the invention is better understood, the same consists in the novel constructionand combination ofparts of a Wei hing mechanism for refrigerators, as will he hereinafter fully described and claimed.

In the accompanying drawing forming a part of this specification and in which like characters of reference indicate corresponding parts: Figure 1 is a View in elevation,

partly in section, of the-upper portion of a refrigerator, showing the improved mechanism therein.- Fig. 2 is a,v1ew similar to Fig. 1 but viewed at right angles thereto. Fig. 3 is a fragmentary detail view showin the indicator.

lteferrin to the drawing, R indicates generally t e up er portion. of a refrigerator and I-the or inary ice rest, and asthese parts may be of-the usual or any preferred constructlon, detailed description thereof is;

deemed unnecessary.

Arranged within the ice chamber is the weighing mechanism which consists in part of aplate 1 longitudinally reinforced by L- shaped braces'2, which as shown in Fig, 2, extend nearly throughout the length ofthe late. ower platform P are four coiled springs 3,

60 the upper coils of which 'are sprungaround Interposed between the plate and the washers 4 that are firmly rivetedto the plateand the lower ends of which are sprung,

around bosses '5 rigid with the platform.

The registering mechanism comprises a rack bar 6 that works in acasing 7 secured to the lower platform and pro ectsat its lower end through the base plate 8 of the casing, and is provided with a toe 9 to limit its upward movement, the lower platform being provided with an opening 10 to per mit free movement of the: bar. Surrounding the rack bar is a coiled spring 11, one end of which bears against the top of the casing 7 and its other end against a head or knob 12 carried by' the bar. The bar is of such length that when the refrigerator is empty the knob contacts with the plate 1, and thus insures accurate weighing. En-

gaging the rack bar is a pinion 13 that is carried by the inner end of a rod 14 journaled in the casin' 7, the outer end of the rod being projecte through one wall of the refrigerator and being provided with a hand or pointer 15 to traverse a graduated dial 16 secured to the refrigerator.

As will be obvious,l to insure proper operation of the device,.all of the springs and the parts of .the indicating mechanism must be made of a non-oxidizable metal, preferably brass to prevent rusting.

A very important feature of this invention resides in the fact that the rack bar is disconnected from the plate 1, so that the operation of the former will not be interfered with no matter how the ice is disposed upon the plate 1, and by this simple expedient, an ob'ection heretofore present in apparatus' of this character is completely overcome. Furthermore the plate 1 with the springs- 3.may easily be removed when desiredto cleanse'the interior of the refrigerator, and thereby-render. the latter thor ou hly sanitary.
